ForestryWelded Mill and Drag ChainSectionMill Chain from <strong>Tsubaki</strong> is manufactured by welding side bars to separately formed barrels (bushings) and pins. Welds fuse each endportion of each barrel to an adjacent side bar end portion to create high fatigue resistance. The end portion of each through hardenedpin is tight fitted onto the side plate and riveted for maximum strength. Special design considerations include enlarged shoulders fortight press fit in the sidebars and tapered construction for rapid assembly. <strong>Tsubaki</strong>ʼs oversized rivet head outlasts conventional rivetheads. The result is a mill chain that is designed and made to offer strength, precision, impact resistance and wear resistance. Thisresults in a chain that is built to withstand both punishing shock load and abrasive conditions. And each component is engineered totight tolerances. This kind of chain is found throughout the world in lumber mills, pulp and paper mills and other industries wheresevere applications demand strength and reliability.BConveyor Chain B150<strong>Tsubaki</strong> of Canada Limited, 1630 Drew Road, Mississauga, ON L5S 1J6 Tel: 905-676-0400 Fax: 905-676-0904 Toll-Free: 800-263-7088 www.tsubaki.ca e-mail: info@tsubaki.ca
